﻿Readme BJPS Replication Materials




The latent measure of external threat can be replicated in R, using the script titled “IRT_Threat_BJPS” and the dataset threatBJPS.csv.


The values reported in Table 1 are also derived from these files, but are saved in “lambda_threat9b.csv” for convenience.


The main results (Table 3) are derived from Stata (dataset threatHR_2.dta). 


The validity analysis and Figure 2 are derived from Stata (dataset threatHR_2.dta). 


Figure 3 is derived from R (dataset threatHR_2.dta). 


The main external threat measure is found in threatmeas.dta or threatmeasure.csv.


The alternative external threat measure that extends to 1919 is in threatmeasure1919.dta
